We separated the core of the document from the tests (previously section 5 in version 1.1). This is as a preparation for the integration of the new WCAG2.0 guidelines into UWEM. A migration plan is provided that describes the steps necessary to update UWEM from WCAG1.0 to WCAG2.0. This has not yet been executed.

UWEM1.2 contains a complete methodology for the evaluation of websites for WCAG1.0 comformance. The document is separated into a Core document and a Tests document. UWEM has been developed by the WAB Cluster in order to improve the Tool and Browser Independence, the Unique Interpretability, Repeatability and Translatability of the WCAG1.0 guidelines.

The UWEM Migration plan from WCAG1.0 to WCAG2.0

The Migration plan presents the migration approach for the UWEM designed by the WAB Cluster, to tackle the challenges provoked by the incorporation of WCAG 2.0 in the methodology, while maintaining the testing framework for WCAG 1.0. This document responds to a formal request from the European Commission's e-Inclusion Unit and the evaluators of the cluster work. The document is relevant to the use of WCAG2.0 by EU and Member States.
